Description
Technical field
The utility model relates to the wiping arrangement that a kind of blackboard wiping is used, and especially can unload the blackboard eraser that changes wiping surface at any time after wiping surface is impaired.
Background technology
At present, known ordinary blackboard eraser is equipped with wiping surface by plate body and on the front of plate body (wiping surface), and wiping surface is made by flannelette, felt or snag, in case wiping surface impaired after, although intact plate body is arranged, also have to discard waste material.
After wiping surface is impaired, has only discarded shortcoming at existing blackboard eraser, the utility model provides a kind of detachable blackboard eraser that changes wiping surface, this blackboard eraser can unload easily and change wiping surface after wiping surface is impaired, guarantees the normal use and the economical with materials of blackboard eraser.
Summary of the invention
The technical scheme that its technical problem that solves the utility model adopts is: the detachable blackboard eraser that changes wiping surface comprises plate body and the wiping surface of being located on the plate body front, technology special feature of the present utility model is, by plate body, correspond on plate body front, the back side, the side coincide respectively cover by outer cloth sheet, fixedly the wiping surface that constitutes of lining cloth, cushion and by outer cloth sheet, approach the fixed bed that artificial leather formulation type lining constitutes and sew up covering into one, be provided with the screw of fastening fixed bed in the plate body back side.Plate body can be made cuboid with timber, plastics, metal, but the most handy timber is made, and is in the wiping surface on the plate body front, and the front of its size and plate body adapts, the skin that it is made by the cloth sheet, peripheric surface place below outer cloth sheet is stitched with fixedly lining cloth, fixedly is stitched with cushion below the lining cloth, and cushion is made with several layers of looped fabric or felt, and be in the centre position of outer cloth sheet, like this, can avoid cushion to be sewn in rubbing surface place on the outer cloth sheet, and cause the disadvantage of the disconnected sewing thread that rubs.Sewing up with the cloth sheet around the outer cloth sheet of wiping surface longitudinal and transverse is outer field fixed bed, and sewing up below the outer cloth sheet of fixed bed with thin artificial leather fixture has the typing lining of thickness once, because the artificial leather tension is not yielding; The plate body back side is provided with the containing position line, even the geomery of fixed bed should be able to satisfy the side and the back side of containing plate body, is provided with the screw that can make fixed bed be fixed in the plate body back side on the plate body back side.At this moment, if the blackboard wiping surface is impaired, as long as will be sewed with the covering that wiping surface and fixed bed are seamed as a whole, wiping surface is covered and aligning plate body front, contain whole plate body respectively at the position that adapts, and be as the criterion, tighten covering from longitudinal and transverse direction with the position line of being located at the plate body back side, be fixed tightly on the plate body back side with screw, pad from vertical, horizontal respectively then, can normally use; The material that the utility model adopted can be useless cloth, tailing, and plate body is reusable, thus after realizing that the wiping surface of blackboard eraser is impaired, can unload at any time change wiping surface and turn waste into wealth, the purpose of economical with materials.
The beneficial effects of the utility model are, not only can make the wiping surface of blackboard eraser impaired after, unloaded at any time and changed wiping surface, and adopt useless cloth, clout to make, and turned waste into wealth, have favorable economic benefit and unload change, easy to use.
